Which reaction from following occurs at $2000 \mathrm{~K}$ in the blast furnace for extraction of iron?

  • A
    $\mathrm{CaO}+\mathrm{SiO}_{2} \longrightarrow \mathrm{CaSiO}_{3}$
  • B
    $\mathrm{CaCO}_{3} \longrightarrow \mathrm{CaO}+\mathrm{CO}_{2}$
  • C
    $\mathrm{Fe}_{2} \mathrm{O}_{3}+3 \mathrm{CO} \longrightarrow 2 \mathrm{Fe}+3 \mathrm{CO}_{2}$
  • Correct answer
    D
    $2 \mathrm{C}+\mathrm{O}_{2} \longrightarrow 2 \mathrm{CO}$

Solution

At bottom of furnace, 2000°K occurs, and here Carbon reacts with oxygen to give Carbon mono oxide

Hence, the correct answer is option: 'D'.
